Trump-Ukraine inquiry: Democrats demand documents from White House bbc.com

US Democratic lawmakers have demanded documents from the White House as part of their impeachment inquiry into President Donald Trump.

The documents relate to a call between Mr Trump and Ukrainian President Volodymyr Zelensky on 25 July.

In the call, Mr Trump pushed Mr Zelensky to investigate his leading Democratic political rival, Joe Biden.

The impeachment inquiry stems from the call, which was flagged up by a whistleblower in August.
